Listed in the data table are amounts of strontium-90 (in millibecquerels, or mBq, per gram of calcium) in a simple random sample ofbaby teeth obtained from residents in two cities. Assume that the two samples are independent simple random samples selectedfrom normally distributed populations. Do not assume that the population standard deviations are equal. Use a 0.05 significancelevel to test the claim that the mean amount of strontium-90 from city #1 residents is greater than the mean amount from city #2residents.Click the icon to view the data table of strontium-90 amounts.What are the null and alternative hypotheses? Assume that population 1 consists of amounts from city #1 levels and population 2consists of amounts from city #2.OA. Ho: H₁ H₂H₁: H₁ H₂о с.
